Wilson, to recap... The original installation was 100 ft tall with a large wind generator on top. The three piers were 18 inches in diameter and 7 ft deep. After spending a few minutes thinking about
When anyone comments on the slight lean just explain it is a finely calibrated lean to adapt the polarization to cancel the coriolis effect on the Poynting vector and if it had been done in the south
As is everything practically in any engineering situation, tradeoffs are the essence of decision making. Requirements vary so solutions vary. Given the statistics on outages in my area, I do not anti
What about putting something over the rotation loop coax? How about the corrugated black plastic wire loom covering? Or better, maybe a cloth cover made from sun resistant awning material. Even I cou
My backup genset will power my electric raise and lower crank-up tower when installation is completed in addition to my workshops where I work on tower components and antennas. As a spin-off benefit
Manual or electric crank up/down?? A thunderstorm or other situation develops with possible high winds. Would you rather throw a switch from inside the shack or go out in the rain/hail and risk elect
Diligence is a good thing but weather forecasts don't always play out as predicted. As I previously described, I had myself and 3 others converge on an older hams QTH for a "Tower Raising" but... Alt
If you don't find a control box you can make one easily. It is just powered by a small wall wart (or other supply.) It is the equivalent of a single pole 5 throw switch. It is a rotary wafer switch w
I have a Hy-Gain Hy-Tower of '1950's design originally intended as a 5 band antenna (predated WARC bands.) It has been improved (more stainless) and you can add on a 17 meter stub. It works 12m just
Anecdotal results are meaningless. 73, Dave AB7E It depends. Sufficient anecdotal results can be statistically significant. Certainly a sample of one where Joe Ham says he used a salted wet noodle an
I have the LDG AT-1000 Pro II tuner with accessory analog meter. I would like to remote the meter and the push buttons (in the shack) so the tuner can be closer to the antenna farm. Has anyone tried
August gentlemen of the elevated antenna mounting structures fraternity, I would like some technical advice (and anecdotal reports are also solicited as well) regarding the necessity/effects of break
Steve, thanks for suggesting the obvious which I had blissfully overlooked. Well, du-uh why not just give it a whorl? Id suppose if it were an issue then when rotating a directional antenna on that t
Ah, there is a possibility. I hadn't thought about using guys as inverted V sky wires. In order to not have the angle of the wires too vertical and still not have to place the guy anchors really far
My plan for an antenna farm is as follows: I have a Hy-Gain Hy-Tower vertical atop a metal barn roof that operates 160, 80, 40, 20, 17, 15, 12, and 10M. I have a 270 ft Carolina Windom OCF dipole hun
I think I got it... Phillystran (or other non nonconductor good... steel bad... Anyone with a reasoned opinion re my question regarding VHF and UHF antennas on a tower? At some point breaking the guy
George, thanks for the rundown. I will try steel for my 40 ft crank-up tilt-over which will only have VHF and UHF on it. How far away from my Hy-Gain Hy-Tower or a 50 ft grounded tower with 6 band HF
While on the grounding topic... why do some sources recommend burying the wire clamp to copper ground rod connection a minimum of 6 inches? Patrick AF5CK --Original Message-- From: Alan NV8A Sent: Su
Gene, I didn't think the 6 inch burial related to squeezing a little more depth out of the rod but was supposed to confer some advantage. What advantage was not mentioned, just info from the tower mf
My good friend and experienced mechanical engineer (35+ years of hands-on experience) says the stronger option is worth the difference. It doesn't make a better dead weight but it does stay together
